If it actually what happened, then it's like you're winning. Yeah, so there's people playing with the orbs of light. So yeah, lots of projectors, massive projectors, but in 2013 I added some lasers, right? So everything since 2013 has all been about lasers. Everything I do now is lasers. Here's a short video of the thing. Oh, I haven't got any audio. Can I plug in the audio? Sorry, you don't really need the audio. It's just music, but we got a cable. It's over there, isn't it? Cables over there. It's fine. Don't need music. So yeah, there you can see one of the big massive projectors. This was in Nottingham. That's the screen going up. That's some infrared cameras to do the motion detection. Yeah, so we realised we could rig the screen on those scissor lifts and it's quite an efficient way of doing it. I mean, don't get me wrong, it's still massively expensive, this project. That was the laser. Yeah, just in terms of the crew and the health and safety evacuation plans, months of planning. Yeah, it's a complicated project, but I really, really love it and people seem to get excited. The first time I ran it, I just used projectors, but then I added the laser to try and pick out bright spots. I don't know if you can see those little bright bits in there. That's what the lasers just kind of emphasising. And as this tour went on in 2013, I just added more and more lasers. So this was like the first stop, so I hadn't really added that many lasers at this point. But yeah, we bring out this massive 10 watt, 11 watt laser, I think I should say. So this little laser in my pockets, this one, that's pretty cool, that's pretty bright laser. This is half a milliwatts, right? So obviously an 11 watt laser is 22,000 times brighter than this. I'll also add space invaders, right? Just add a game to everything that I do. That's just what you have to do. Oh, and asteroids. So with asteroids, every bullet is rendered by the laser. The laser scans around and turns on and off. So literally mirrors are moving around a single very bright laser. I'll talk a bit more about that later if you're interested. In fact, yes, I'm also going to be talking about that tomorrow at the open source hardware camp. So I'll go into even more geeky details tomorrow if you're into that sort of thing, which you are, right? Yeah, yeah, okay, good. So once I'd learnt how to use lasers, oh, I meant to have another slide in there. Once I'd learnt how to use lasers, I just wanted to use lasers all the time. Oh, I wonder where it is. I've lost a video. That's fine. It's somewhere here. No, no, no, no, no. Oh, I've lost that video. Okay, we didn't need that video, but basically I made a massive laser thing. And I'll show you that tomorrow. Yeah, it's pretty good. I'm publicising tomorrow's event. Right, where was I? Down here. Right, laser light synths. So tomorrow officially I'm talking about laser light synths, but it's another project that I made, obviously using a massive laser. But I designed and built these light synths, which are musical instruments completely covered in super bright LEDs, neopixels. And they're designed so that anyone can play them. So you get to be in the band for one night, right? That's the finished article there. And as you play, obviously they light up bright colours, but also lasers kind of fly up the wall, projecting shapes as you go. Yes, so tomorrow that is when I'm going to be talking about this. And I'm going to be going into massive details about how those synths are built and made and programmed, and also the lasers. This is the slide that I lost. It's back, yay. Okay, so this was when I'd learnt to use a laser. I just put a laser in everything. I made this intro sequence for a conference. So with conferences you usually have some nice animation on the screen, but a little way into it I thought I'd break out of the screen with the laser and project all over this massive domed building, which is the Oxford Town Hall. So you can see we can cover quite a big area with the lasers. And I don't know if you saw the initial picture of the building. There's a big pipe organ in the middle. So obviously I had no choice but to turn it into a graphic equaliser, right? You just have to. It's like a massive pipe organ, graphic equaliser. That's, yeah, I had no choice. Also, I mapped the space in 3D so I could project lasers on as though they were mapped onto the three-dimensional architecture of the building. So for this effect, it actually looks like there's kind of a ring of lasers, even though it's just on the back wall. Okay, let's move on. So retro, right? I love retro technology. I guess I'm that sort of age where I, you know, I learned to programme on a Commodore Pet, I should say. Commodore Pet even before the Commodore 64. And back then computers had attitude, right? They didn't really have nice shiny icons or anything like that. They literally would do nothing, right? You're just type stuff, hello, enter, syntax error. It's like there were the most, computers were mean by it in those days. They were so mean. All I wanted to do was draw pictures and make animations. So really that's why I learnt to code, right? It wasn't because I wanted to be a programmer. It was because I wanted to draw pictures and we didn't have Photoshop or After Effects or any of those creative tools back then. We literally had to learn to code. Really my career has just been a continuation of that concept ever since. But yeah, I love ripping apart old hardware obviously because it's just there's an elegance and simplicity to it that is quite beautiful. So this is a joystick from an Atari 2600. You see that circuit board there? I mean, I think that's probably hand drawn, right? And so, you know, it's obviously a much simpler time and these contacts there are just sort of metal plates on top of the circuit board. When you depress them, they make the connection. So it was even, I guess, before like decent microswitches with that available. It's interesting actually because the laser gun that I'll be talking about in a minute actually has a nice microswitch in it. But that was like maybe three or four years later from this. So you're like very different. You might see there that I've hacked into it a trinket pro into that joystick. So now this is a USB joystick. Oh, you can see me doing it there. I've got a nice video. Oh, you don't need to see any of that. You can see the light going on. So the trinket pro can just pretend to be a USB device. A lot of Arduino's can actually. So you can just, or Arduino compatible things. So you can just attach an Arduino to it and then instantly convert this joystick to a modern device. And I even used the same connections on the circuit board so I didn't even have to like rip it apart too much. Casio vltone keyboards. Yeah, they're quite amazing as well. I learned how they worked recently. I learned the whole history of Casio, which I could, I did a whole talk about the history of Casio and calculators. It was brilliant. I talked about the most famous Casio calculator ever, the FX501P, right, which you obviously all know. I know like you don't even think you know it, but you do know it because Kraftwerk wrote a song about it, right? It was actually literally that calculator and that calculator makes the blippy noises that is in Kraftwerk's pocket calculator song. So, yeah, you do know it. Anyway, this is quite fun because it's a keyboard. Probably you had one, right? There were millions of them, right? Did you have one? Yeah, you still got it. Of course you have. I've got a couple. They're kind of nasty, but they're so revolutionary. And if you sort of dig into it and find out how they work, it's even more incredible. The most brilliant thing is that they, you know, they could, I think they were 50 pounds at the time, right? I think it was like about 1981. I can't exactly remember. That was quite a lot of money then for a toy. So in order to just help sell it into your parents, well, they added a calculator into it. So you can see the number keys along there. You can actually do all your favorite songs with this song. And it's quite funny because there is actually a synthesizer built into this. So it's got some really nasty presets, right? But it's also a synthesizer. And the way you program the synthesizer is by saving an eight-digit number into the memory in the calculator section. And then when you switch it over to the keyboard section, it plays a sound using that number. And each digit in the number changes a different setting of the synthesizer. It's absolutely bonkers. Anyway, I love this stuff so much. And I love ripping it apart. And I love learning way too much information about them to be credible that I thought I'd make a new show. So I've got this new show called Hackton Classics. And it's kind of terrifying, right? Because it's like a 60, 70-minute show in a theatre, right? So it's a stage show where I just kind of have to talk about stuff and make demos and try and be entertaining. But I'm really, really excited about it. And it's got its premiere, I suppose. It's the 28th of September in the old market, which is a venue in Brighton and Hove. Officially Hove, right? But it's all the same. It's all one city. So if you're in Brighton, there's loads of digital festival stuff. I live in Brighton, by the way. There's loads of digital festival stuff happening in Brighton all month. So there's loads of cool stuff. So whilst thinking about things I could do for this show, I bought some Nintendo light guns. They're the Zappa. I believe from the... Oh, I'm not even sure when, actually. I think 82, maybe? Who had one of... Who had these? Right, so you know the game, right? It's the NES Nintendo console. What game did you play with it? Duck Hunt, of course. Everyone played Duck Hunt. That was the game that came with these light guns. And there was this dog who was such a bastard, right? He was basically... Oh, it's quite a brutal game, right? You shoot these ducks and then the dog's like, hey, like dead duck. And if you missed them all, he'd laugh at you. And everyone wanted to shoot the dog, but it didn't ever work. And you know, maybe I'll make a version where you can shoot the dog. I don't know. It's like the pacifist version, or the animal... Well, not exactly. The duck friendly version. I don't know. Anyway, so I made a project a few years ago in 2014, 2013, 2014, where I wanted to recreate a shooting gallery with modern technology, but with kind of real missiles in the guns. So I actually got a load of Nerf guns and used those to make this sort of laser-powered target shooting gallery. So the target you see there is projected with a one-watt scanning laser. So they're fairly traditional, you know. They're fairly traditional lasers, but they're getting faster and more powerful and cheaper all the time. So my one-watt laser, I think, was about £1,200. RGB, so it's got all the three colours. It can mix them together and do any colour you want. This project was mad, actually, because in order to detect where the bullets went, I actually had an array of microphones, so that you can see it there. And I'd measure the amount of time it took for the sound to reach each microphone. That was just absolutely bonkers. And it was kind of like my bizarre kind of plan B, right, when my plan A didn't work. So I had to use my bizarre plan B, which worked really well. So this was a really fun project, but I'd had to spend all weekend on my knees, hands and knees picking up Nerf Gun darts, right, so it was not fun. So I thought, well, wouldn't it be more fun to have an actual laser gun? So I've been trying to figure out what kind of gun. I've been looking at toy guns, and they're always either a bit too, like, gunny. I don't really like guns. There's an actual real thing in the world, but I quite like laser guns, right? That's okay. You can like fake guns and hate real guns. I don't know. I'm conflicted. I don't know how to square this one. Anyway, I wanted a gun that wasn't obviously like a proper scary killing people type gun, but it was really hard to find a decent quality gun, and it was then that I remembered about these Nintendo Zapper guns. So I bought them. So there were millions of these guns made in the early 80s. They were really popular, and because they just don't work anymore, right, because they need proper old-school cathode ray tube TVs with zero latency in order to work. It's actually quite fascinating how they work. They're rather beautifully made. The other great thing about them is that they're really solid. They're actually really nicely made. When you open one up, you really get an impression of that. But let's just think about how they're made, how they actually work to start with. Well, we've obviously got the cable coming in here. This is the sort of trigger mechanism. You can open that up and there's some springs and a catch inside there. I should take a picture of that later. But there's the micro switch. So now we're at the stage of having modern micro switches, really clicky and nice quality switch. Then we've got some electronics here. Inside this metal kind of shield, there is like a photo cell, I think. It's like a light-dependent resistor. It's certainly a light sensor of some description. Then here we've got a lens. The thing about these light guns is they don't produce light at all. You'd think they were projecting light out, but you'd think that was like an out-hole. But actually it's an in-hole. Stuff's going, actually that sounds weird. It's a receiver. It's not a transmitter. It's fine. What happens is when you pull the trigger, it tells your NES that you've pulled the trigger. Then what it does is kind of mad. If we look at the screen back here, what it does is it actually clears the entire TV to black for one frame, for 1.50th of a second. Then it draws a white square wherever the duck is, so there'll be a white square around this duck. Then it will go back to the game again. If the little sensor in the gun sees black and then white, it knows that you've hit the duck. Because through the lens it's only looking at that tiny bit of the telly that it can see. So if you just see black all the time, then it knows that you haven't hit the duck. So it's really rather clever, isn't it? It's really cool. I know way too much about that stuff as well. They actually did an old version, in which they'd install into bowling alleys. This would be in the early 70s, I think, or maybe even older. They'd actually project ducks that flashed up into the ceiling. Similar sort of light gun mechanism, though. Absolutely mad. I must get some video for my show. So there's other really nice things about this. Do you know what that is? Any guesses? Some sort of lens? No, it's not. It's literally just a bit of metal with a hole in it. It's two sort of semi cylindrical halves of a tube, I suppose, and the light gun sees through that. It's just for a weight. Then there's another weight here. So it's like those two things are just to make the gun feel better. So it's a really nicely made bit of gear. So I thought, let's rip it apart, but I sort of wanted to do it like the joystick and the Atari joystick. I didn't really damage too much of the original gun. So I just thought, I'll take out the main circuit board. That's the old circuit board there. This is my new circuit board. Sorry about the noise. It must be going through HDMI, I guess. It's just when I do the laser. I'll tell you what, I brought another laser. Actually, I brought this one, but that doesn't... I've run out of battery, but I brought this one, which is really cool, check this out. It's got a key, so you know it's scary, right? When a laser's got a key, you know it's scary. Whoa, look at that. That's kind of cool. Let's take the diffraction grating off. It's meant to be five watts this laser. I can't quite believe that. I'll just be ridiculous. It's properly blinding. So let's use this one. I literally can't use this laser, it's too bright. Anyway, what was I even saying? Right, so I took out this... Let's go back to this one. So I took out this... This was the original circuitry there, and I replaced it just with a bit of strip board, right? I put in a teensy, which is a 32-bit Arduino compatible board. So I used a teensy. They're really cool. I used them in the light synths as well. Really nice little things. And there's a laser there on top. It's actually originally I used the laser. One of these laser pointers, which if it had batteries, you'd see it was ridiculously bright. Even though it's meant to be less than five millawatts. Not as bright as this one. This one's just stupid. But it's still really much too bright than it should be. I bought this from China. You've got to be really careful, actually, because these are probably dangerously bright. I'm actually fully trained in laser safety. I've got a certificate and everything, so I'm allowed to use these. But if you're going to play with these stuff at home, just be really, really, really careful. So, yeah, that laser there is like the one in this laser pointer here. Ridiculously bright. I thought, that's it, right? I've done it. It was easy. It took me a day. But then I thought, well... Oh, you're a bit of a close-up there. But then I thought, well... In fact, let's just show you it working here. I've got a video here. You can see that I can pull the trigger and you can see the light flash. And there's a little bit of a... I've got a smoke machine at home, so I just made a little bit of haze in the room. So you can actually see the laser beam. But usually, with the laser, you can't see the beam at all. There's no beam there. Even with my crazy, scary one here, it's like... All you can see is the end, right? You can't see the laser beam. You need a smoke machine for that. So I thought, that's fine. I'll put some neopixels down the side. So then I could actually make the neopixels sort of chase, and then I could do the laser a tiny bit later. So it looks like it's actually moving down the barrel of the gun and then flying out of the gun. That was pretty cool. So those are standard neopixels. They were a bit too big. I didn't really like them. So in the end, I've got some much smaller neopixel-compatible LEDs. You'll see those later. But then I thought, well... It's a bit silly, right? It got a little bit silly, because... I saw... You know, tested.coms. They run and see testers. The guys from Mythbusters, they do loads of cool builds and stuff. And they made a Ghostbuster trap that was 3D printed and they put a smoke machine in it. And the way they did that was with an e-cigarette. And they had an air pump in an e-cigarette and it just made smoke. And I was trying to find out about it, but they sort of glossed over it. They didn't really talk that much detail. And then I found a magician who had made this trick where smoke comes out of his hands and the electronics guy that made that actually documented it on YouTube. So I knew I needed a tiny, teeny little air pump. And if I just blew air into an e-cigarette, then it would make smoke. So once I had this, once I knew about it, I couldn't forget the knowledge that I embarked on a massive journey that would take me weeks to resolve. Which was, I wanted to put a smoke machine in the gut. I just had to. So I don't smoke. I'm not a vapour. I didn't know anything about vaping. I went to the vape shop. They're weird places, aren't they? No, it was one in Brighton. There's several now. I think in most city centres there's several of these places where people go to buy vape machines. I'm sort of equally amazed and horrified by vaping both at the same time. It's a weird other world. Who vapes? Anyone here? That's willing to admit it? Oh, come on. No vapours here. I don't believe you. I think I just embarrassed you in submission into not revealing yourselves. Anyway, I went into the vaping shop and I was like, oh, I'd just like to get a vape thing. And they were like, yeah. They asked me all these questions. I didn't really understand. And they're like, what sort of capacity do you want? I was like, I don't know. I just want really the smallest one that you could possibly have. So there's a garden shop. Very helpful. She demonstrated this e-cigarette by basically vaping right in front of me. She just produced this massive cloud of smoke in one puff. And I was like, holy shit, that is amazing. And she was like, oh, wait. You can see this one, right? And then she took the big one and it literally just filled the entire shop with smoke in one puff. And I was like, OK, no, no, that's too much. I don't need that one. I'll get the small one. And this is the small one that she gave me. And she was like, what flavour vape liquid do you want? I was like, no flavour. I don't want any flavour. And I was like, I don't want any nicotine. I don't want any flavour. And she was like, they all have flavour. I was like, fine. What flavour have you got? She told me all these weird flavours, like strawberry cream and lemon zest and lime and licorice and stuff. Anyway, I was like, fine. You can see in this video my little tiny air pump that I ordered from China and I blocked up all the holes except for one and I put it into the e-cigarette and you push the button to trigger the battery and it blows out a ton of smoke which is kind of cool, right? Obviously I'd have to get rid of the battery. No room for that. But I thought maybe I can just put in electricity some other way. But it was still just a bit too big so then I realised that I didn't need to have spent like 40 quid or whatever it was on this fancy e-cigarette thing. You can just get these tiny little ones and they're amazing, right? They're not obviously as much capacity but they're entirely contained in this filter tip there. That's the entire mechanism for it's got the atomizer in there and all the vaping liquid and everything. This bit, the end which is in a normal cigarette, tobacco that's just the battery and there's also like a pressure switch so it turns it on when you suck the air through it turns on the pressure switch and there's a little light in the end because it's so clever. I'm equally horrified and amazed. I don't know. Anyway, so then I had to obviously embark on getting that into the gun so at this point I had to rip out the original the space where the original went and I took my dremel and ground away all the plastic holding and everything. So I had to actually put the circuitry and the tinsie then into the handle so it got rid of the weight drilled all the stuff out all the plastic bits put this circuit board in that would basically be the tinsie and all the sockets for all the parts. You can see this is the finished just skipped on weeks here by the way. I should just say it took me ages to get this done. Let's talk you through this. This is kind of this is my grand opus. Let's start at this end. So this is the laser and not anymore the laser in the laser point. This is a bigger laser. It's 50 milliwatts from China. These cog type things there are 3D printed. They hold the laser in place but they've also got gaps around the side this here that's the e-sig atomizer and the vape that quid. Here we have a 3D printed kind of duct that takes the air from this air pump through there and pushes it through the e-sig atomizer. You'll notice there's some wires here there's a bit of a sugru the rubber silicon stuff. I wrapped the end of the e-sig in that and soldered some connections to the actual I've basically locked off the thing with the battery in it so I had the screw connectors soldered some wires in blah blah blah so now I can actually replace this e-sig cartridge. I figured out how to refill them as well. They're not meant to be refillable but I figured out how to do it in case I don't want mint smelling ones anymore. Right so then also there's a tiny fan there because although the pump sort of pushes the smoke through I need something else to kind of help to get it out at the end of the gun it's a bit weak. I'd really like a much more powerful fan. So if anyone knows about any fans that are less than about 15 mils in diameter please let me know. Okay so here's the original trigger mechanism micro switch there all the wiring into the teens you see all these connectors there they're just JST connectors from all the various bits. On the circuit board that I made there's loads of MOSFETs to obviously power up in the three volts to power all these things. This draws about a current this draws about 500 milliamps this draws about 300 milliamps probably about two or three amps of power in the end. Yeah and then this cable there is going to the outside of the gun where the neopixel strip is and you can see here actually I figured out then how to get the wiring for the neopixels through the outside and cross from one side to the other through this copper foil connector right so now you don't anyway geeky geeky detail. So you can see how packed in this gun it was ridiculous right but of course I needed like laser gun sounds but at this point it kind of went to shit a little bit. I put in an aid of fruits amplifier that's two and a half watts or three watts I think and this transducer which just basically vibrates really loudly right so it was really cool it just made this really loud sound that shook my entire hand right unfortunately overheated can you see it melted my gun so I had to get rid of that but I'll figure it out next week I promise so the next thing was finding out where the gun was pointing right and then responding to that so I set up an infrared camera now it just so happens that these terrible shitty lasers leak a ton of infrared right which is terrible it's a really bad thing you've got to be so careful because they are really blindy but in this case that's really brilliant because I've got an infrared camera and I've also got a big laser a big expensive proper laser that I can project shapes with it's a scanning laser like the one I had on tour with pixel pyros and that's got really good filters and really good lasers that doesn't leak any infrared so with my infrared camera I can just see the laser that comes out of the gun and not the big massive powerful scanning laser that is my other laser right so you can see now I can actually draw with the laser point so the infrared camera can track where the infrared beam is and it can send that back out to the scanning laser you can't see it unfortunately in this picture I've just bought a new laser 4 watts so not as big as the 11 watt one but still really you can see how bright it is this is in pure daylight and you can see how bright that is so I had all the parts I had the gun I had the smoke machine I had the laser and I put them all together and then you can see that when I fired the gun he actually left a mark so my scanning laser is projecting those marks after reading the positions and here is the video that's gone totally viral on Twitter because once I fired the laser you can see that then I read it in with the camera and made that sort of burst effect you can see the smoke coming out right so that really helps to show the sort of laser beam coming out of the end of the gun and then I installed this project for the first time at the Brighton Digital Festival launch party which was the other night and this I love this video this is a couple of guys in the Brighton Digital scene who are just going to listen to the sounds on this bit ineffectual on these speakers but you get the idea so I only programmed asteroids at this stage because I happen to have that anyway so it's a collaboration one person played on the Atari joystick one person played on the on the light gun I've brought the light gun here actually so now obviously I haven't got my big massive laser all the infrared camera I don't have any of that stuff so you can at least see the the smoke and the lights and everything in action I also have this right this is a dead man's switch obviously my laser safety officer I can't just give members of the public a 50 milliwatt laser because they could blind people with it so I've got this switch so when this laser gun only works when I depress this switch right you can't really hear with the mass spectrometer but the pump comes on it starts vibrating in a very terrifying way and then smoke hopefully starts to come out I don't know I used this one e-cigarette for the whole evening and I haven't refilled it but let's see what happens there you go so you can see the laser comes out at the end of the gun and there's just enough smoke to see that and the more you fire the more smoke comes out as well but you know what you do need is the sound effects so obviously in the absence of a transducer melting my gun I need to actually make this happen through my computer it's a bit of a cheat but there you go what can you do I've probably gone where every time I'm really sorry everyone oh Tim looks at this clock he's got no idea it's fine ok so hopefully it's really not loud enough I need them to go through the speakers but there you go oh I haven't got the button pressed hang on come on smoke there you go the smoke's coming up so yeah just imagine like a at that other end and you'll be laughing while I've got this open I might as well just show you the code oh that's that's Jeff's phone you've got to cut should I answer it for you no no it's a foreign number we've got tracking data on Jeff it's probably India they've tracked him I've programmed this all myself usually laser control software is a monopoly and you have to spend thousands on the stuff so I've spent a few years working out all this if I click my mouse you can see that's the path the laser takes I think I can slow down time as well there you go so you can see that the laser my code is figuring out the best path for the laser so it moves around it stops turns on the laser here's the game asteroid's game you can see the path of the laser as that goes through I also have another game which is a flappy bird but it's a special type of flappy bird how do I reset it that everyone can play so do you want a game of a flappy bird not flappy bird as a hint there because this game responds to audience applause a bit like myself so the louder you are the higher it flies let me just turn off the laser path so yeah do you want a quick game of flappy bird are you ready I don't know if it's calibrated it's impossible to test let's just try it and see what happens in three two one go that was really good do you want to try again to beat your high score of four go a little practice run there okay go again nice job all right so let's what else have I got in my talk I think that's kind of it actually so yeah I'm probably massively over time but so what's next so that is obviously just a very quick early prototype later on in the digital festival I'm going to be making laser duck hunt right so this is me drawing the laser shapes compared to the bitmap that might be a bit complex for the laser we'll wait and see and then laser crappy bird which obviously saw already I don't know really what the point of my talk was anymore I got totally distracted by laser guns but I'm going to be here obviously the rest of the day and tomorrow as well so oh is there a question oh the glow stick thing okay so I've done stuff with audience participation with glow sticks as well where I can sense the amount of motion in the audience if I give everyone glow sticks they can wave them around and I can see how much motion there is so I've got a few projects that use that including one which splits up the audience into vertical strips and each section of the audience is a different band member like so each one has one is bass, one is drums, one is guitar one is keyboard and the more motion there is in that strip the more dynamic that instrument is obviously it's a cheesy 80s band as well because it's got to be so that's something I'll be doing at my show at the end of September tickets available now hacktonclassics.com thank you for allowing me to do that terrible plug I think that's probably all I've got time for but thank you so much for listening come and find me if you've got any questions but brilliant thank you so much
